HINGE.

Application filed April 25, 1923. y Serial No. 634,414. ,l

To all iii/0my t may concern.'

Be it known that I, CHARLES N. CoiirnLL, residing at Mainaroneck, in thecounty of Wvestcliester, State of New York, have invented certain newand useful Improvements in Hinges; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to a hinge construe tion particularly adapted foruse in connection with closures on small receptacles.

The ordinary hinge consists of interlitting and aligned knuckles,designed; to swing about a common pintle. To employ such a hinge inmounting covers on small boxes necessarily involves providing both bodyand cover with hinge knuckles. I/Vhere the parts are of metal theseknuckles may be soldered on or made integral with the part with whichthey are to function; but in either event, production difculties areinvolved, and when the box is an article of iewelry its appearance isnot improved. The object of this invention is to minimize thesediiiiculties; devising a cheaper hinge construction for closures onsmall receptacles, while at the same time making a better looking andneater joint. I have done this by providing only the body part of thereceptacle with a knuckle and pintle, while curling an edge of the coverto embrace the piutle ends and perform the function of a. knuckle. Thecurled edge is cut away for a space corresponding` to the knuckle, and'the curvature of the knuckle, made substan tially that of the coveredge, so that when the cover is closed the hinge is hardly noticeableand thus does not detract from the ap pearanc'e of the box.

In order that the parts may be easily assembled, the curled edge of thecover does not completely enclose the pintle, but extends only half-wayaround it. In assembling. the projectingr ends of the pintle are movedtransversely under the curl of the cover edge, and when the cover isswung open the knuckle itself prevents disengagement and the parts areinterlocked. To prevent disengagement when the cover is returned toassembling position, I provide the cover with a bezel, or itsequivalent, which is slipped into place after the parts have beenassembled, and the cover swung Yinto interlocking positoi In theaccompanying drawings,- vI have illustrated a small vanity case or boi;vembodying the invention. 'Inthese drawings, 4

shown in closed position; Fig. 3 isan enlarged detail of the hingeconstruction, the

cover being shown` in wide open position; Fig. 4 is a transverse sectiontaken alo-ng line 4`4 of Fig. 3, `and showing one means for locking thecover in position; Fig. '5 is a vertical section `taken"along line 5 5of Fig. 3, showing moreclea'rlyfthe relation of tliehinge parts; andFigjisa ysection simi# lar to Fig., 4 but showing' a bezel` for lock,`

One ofthe side walls4 one end of the cover are designed to enclose theextending ends of the pintle, the edge at this end being cut away toform an open slot 9 slightly longer than and designed to receivetheknuckle, to permit the cover t0 swing aroundit.

. To assemble the parts. the cover is placed' upon the body and slidlongitudinally until the curled edge embraces the extending ends of thepintle and the hinge knuckle lies within the slot cut for it. The coveris then swung open and the ing position. K

If the cover were never to be closed again, this would be sufficient,but when closed, it is clear that a reverse slidingmovement woulddisengage it. necessary to place some lockingmeans within the cover. Asshown in Figs. l', 2, 3 and"A and 4, the frame l0 which holds thepowderand rouge compacts serves to performthis function. As shown in Fig. 6. Imay substitute a bezel 1l in place of the frame l0.

for preventing longitudinal movement ot.

the cover relative to the pintle.

The hinge construction shown is simple and effective, is much lessexpensive to pro- To prevent this, it

parts are in interlock# duce in quantity than the ordinary twoknucklehinge, and when used in connection with small receptacles, such asshown, produces a very neat appearance, the hinge itl'other memberdesigned to receive the ends of thepintle transversely during assemblyvand tobe swung into interlocking position,

the curled edge being provided with an open slot slightlylonger than anddesigned to lreceive the knuckle, and means for lecking the partsagainst disengagenient when inassembling position.

- 2. ln. a receptacle comprising a body and a cover, the combination ofa hinge knuckle on thebody, a pintle coaxial therewith extending beyondthe knuckle at both ends,

' a curled edge, on the .cover designed to receive the ends'o'f thepintle transversely when the ycover is closed and forni an interlockingjoint when open, the curled edge being provided 'with an open slotslightly longer than and designed to receive the knuckle, the base ofthe slot co-operating with the knuckle 4to prevent disengagement of thecover is open, and means held` a cover, the combination of' a hingedknuckle 4on the body, a pintley coaxial therewith extending beyond tlieknuckle at both ends, a curled edge on the cover designed to receive theends of the pintle transversely when the cover is closed and to 'form aninterlocking joint when open, and a compactl iframe within the cover forpreventing transverse movement ofthe cover relative to the pintle, thuslocking the parts against disengagement when closed.
